Chaikasem, who turns 77 in August, has extensive government experience: a former attorney general, he served as Minister of Justice under former Prime Minister Yingluck Shinwatra—Thaksin’s sister and Paetongtarn’s aunt—until that government was overthrown in 2014.

Thailand swore in new Cabinet members Thursday with its government in flux after the Constitutional Court suspended the prime minister less than a year after the same court removed her predecessor.

Paetongtarn Shinawatra, Thailand’s youngest prime minister and scion to the country’s most prominent political dynasty, may lose power barely a year after taking the top political office.
